Aardvark (Orycteropus afer)
Aardvarks have a unique appearance. With a high arched back, long pig-like snout and long pointed ears, these secretive animals are mainly nocturnal and grow to around 110 cm in length. They are short and stocky, with a shoulder height of around 60 cm and a tail length of around 60 to 70 cm long.
Aardvarks are equipped with muscular, short legs covered with long dark fur. They have strong, powerful nailed claws that are ideal for digging and walking through the bush in South Africa. While their back legs have five digits, their front legs only have four. Their long snout-like noses are covered in short hairs, perfect for sniffing out prey in the dark.
Their tails and ears are long and both taper toward the end. The aardvark has a unique set of teeth, as they grow only to the back of the jaw and can re-grow simultaneously. Their teeth are not covered in enamel like most animals, but instead are covered in a unique cement-like substance.
The aardvark is an insectivore. It uses its long snout to sniff out termite hills and moves in a zigzag pattern to find its prey. Using its powerful claws, it can easily tear down termite hills and start feeding. Using its long projectile-like tongue, which is covered in a thick adhesive saliva, it can trap many insects for ingestion at a time. As a result, the Aardvarks teeth have evolved to flat, grinding structures to crush the hard shells of various insects. Aardvarks are also fond of melons.
Aardvarks have no specific mating season and they only produce 1 offspring at a time. Baby aardvarks are pink and hairless at birth. They are weaned for a period of 7 months and reach maturity at around 2 years old. For the first two weeks of their lives they stay within the burrow, then they accompany their mothers above ground.
The aardvark is mainly a solitary and quiet animal. It is nocturnal and does all its hunting and burrowing at night. Occasionally, they sunbathe outside their burrows during the day. Aardvarks dig burrows up to 13 cm long and have numerous little tunnels branching off the main one. Aaardvarks burrows for shelter, food, protection and raising their offspring. The aardvarks long ears make for excellent hearing in the dark, however, they have poor eyesight. When threatened, the aardvark makes grunting and bleating sounds. They are also excellent swimmers.
Where They Are Found
The aardvark hails from sub-Saharan Africa and South Africa. Its natural environment consists mainly of savannah and grassland where the ground is soft with plenty of food and water resources. Aardvarks avoid forested areas and dry, rocky desert environments.
